[0002] Aluminum alloys are widely used in aircraft manufacturing, machinery manufacturing, and other fields due to their excellent formability and high specific strength. To ensure the quality of purchased materials, manufacturers generally need to test the mechanical properties of aluminum alloy materials when purchasing them. Processing of test specimens is essential. When purchasing metal plates of multiple grades or specifications, the long processing cycle will delay the material's factory re-inspection. During factory re-inspection, standard tensile test specimens must be processed and then subjected to mechanical property testing. Using previous processing methods, tensile test specimens of the same size cannot be milled in batches, which will seriously increase the processing cycle of tensile specimens and cause serious waste of manpower and material resources.
